1N4752A_S00Z Zener Diode Equivalent & Substitute Parts

Part Overview

The 1N4752A_S00Z is a 33 V, 1 W Zener diode manufactured by onsemi in a through-hole DO-41 package. This component is classified as obsolete, necessitating identification of active equivalent alternatives for new designs and production continuity. Substitute parts must maintain identical electrical specifications and mechanical compatibility to ensure direct replacement without circuit redesign.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the 1N4752A_S00Z are qualified based on the following criteria:

Electrical Parameters (Critical):

• Zener voltage: 33 V nominal
• Power dissipation: 1 W maximum
• Voltage tolerance: ±5%
• Impedance: 45 Ohms maximum
• Reverse leakage current: 5 µA @ 25.1 V
• Operating temperature range: -65°C to 200°C

Mechanical Parameters (Critical):

• Mounting type: Through hole
• Package designation: DO-41 or DO-204AL equivalent
• Axial lead configuration

All identified substitutes meet these electrical and mechanical requirements without deviation. Substitution is based on parametric equivalence, not functional similarity or performance assumptions.

Engineering Selection Recommendations

1N4752A (Lumimax Optoelectronic Technology)

This substitute is an active product with full parametric equivalence to the 1N4752A_S00Z. The part is RoHS compliant and maintains all electrical and mechanical specifications. Inventory availability is substantial at 18,715 pieces. This option is suitable for applications requiring RoHS compliance and long-term supply continuity.

1N4752A BK PBFREE (Central Semiconductor Corp)

This substitute is an active product with full parametric equivalence and ROHS3 compliance. The lead-free designation (PBFREE) indicates compliance with lead-free manufacturing standards. Inventory is available at 809 pieces. This option is appropriate for applications with strict environmental or regulatory requirements.

Both substitutes are electrically and mechanically interchangeable with the obsolete 1N4752A_S00Z. Selection between them depends on supply chain requirements, compliance certifications, and inventory availability for the specific application.

Frequently Asked Questions (FAQ)

Q: Can the 1N4752A (Lumimax) directly replace the 1N4752A_S00Z (onsemi)?

A: Yes. Both parts share identical electrical specifications (33 V, 1 W, ±5% tolerance, 45 Ohms impedance, 5 µA reverse leakage) and mechanical configuration (DO-41 through-hole package). Direct substitution is supported without circuit modification.

Q: What is the difference between 1N4752A and 1N4752A BK PBFREE?

A: Both parts are electrically and mechanically equivalent. The primary difference is the lead-free (PBFREE) designation on the Central Semiconductor part, indicating compliance with lead-free soldering standards and ROHS3 certification. The Lumimax part is RoHS compliant. Selection depends on manufacturing process requirements.

Q: Are there package differences between the substitute parts?

A: All three parts use the DO-41 package configuration with axial leads. The supplier device package designation varies slightly (DO-41 for onsemi and Central Semiconductor; DO-41G for Lumimax), but these represent the same physical form factor and are mechanically interchangeable.

Q: Why is the original 1N4752A_S00Z marked as obsolete?

A: The onsemi 1N4752A_S00Z is classified as obsolete, indicating it is no longer in active production. Active equivalent alternatives are available from Lumimax and Central Semiconductor to support ongoing applications and new designs.

Q: What compliance certifications should I consider for substitution?

A: All three parts maintain REACH Unaffected status. The Lumimax substitute is RoHS compliant, and the Central Semiconductor substitute is ROHS3 compliant. Selection should align with your application's environmental and regulatory requirements.

Q: Can these parts be used interchangeably in existing PCB designs?

A: Yes. The through-hole DO-41 package and axial lead configuration are identical across all three parts. No PCB layout modifications are required for substitution.
